Abstract (en)
[origin: US4670375A] Disclosed is a light-sensitive silver halide color photographic material comprising a support and a plurality of silver halide emulsion layers on the support, the emulsion layers being substantially identical in color sensitivity but different in sensitivity and containing at least one of a dye image-forming coupler, characterized in that silver halide grains contained in at least one layer of the plurality of silver halide emulsion layers consist substantially of monodispersed silver halide grains, a color concentration of the emulsion layer comprising the monodispersed silver halide grains being within the range of 60 to 98% of the total color concentration of the plurality of silver halide emulsion layers. The employment of the monodispersed silver halide grains of this invention and the increase in a concentration of the grains in the emulsion layers permit the improvement of graininess, the enlargment of exposure range and better of stability to processing and stability with time.
